Application filed December 10, 1914. Serial No. 876,448.

. To all whom it may concern scribed and more particularly pointed out lower sash from Be it known that LUmrssns G. SCHWARTZ, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators or Storm-Shields for Windows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, an to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in ventilators or storm shields for windows and consists of the matters hereinafter dein the appended claims.

The invention relates to the type of ventilator or storm shield which is designed to be located on a window sill adjacent the plane of the window opening, to prevent the incoming air that passes below the raised being directed horizontally into the room and thus subjecting the occupants to a direct draft and instead to direct the incoming air upwardly adjacent the wall in which the window is located.

, The object of the invention is to provide a ventilator or storm shield of the'kind described which is cheap .to manufacture, which may be quickly applied to or removed from a window without the use of tools and which is adjustable in length for use with windows of different widths.

The various advantages of my improved construction will appear more fully as I proceed with my specification.

In the drawings: Figure 1 is a perspective view illustrating my improved ventilator or storm shield, the same being broken away at the top and bottom to show its construction. Fig. 2 is a view representing a vertical section through the sash and sill of a window provided with my improved ventilator. Fig. 3 is a view representing a transverse section of Fig. 2 in a plane indicated by the line 3-3 of Fig. 2. Fig. 4 is a view similar to Fig. 2 showing a somewhat modified form of the construction of my ventilator. j

Referring now to that embodiment of my invention illustrated in Figs. 1 to 3 of the drawings, 10 indicates a window casing, 11 indicates the lower window sash which is adapted to be raised and lowered in said cas- -strips 14 of the window frame.

ing, 12 indicates the window sill and 13 and 14, the vertical strips which provide a groove 15 in which the lateral marginal part d manner that the one may be telescoped upon the other for the purposes of adjusting the length of the ventilator to accommodate it to windows of different widths.

The ventilator has an upright base wall 19 and an inclined shield wall 20 which rises from the base wall 19 and is inclined in a plane away from the upright plane of the base wall 19. The inclined shield wall 20 is provided. at its ends with integral flanges 21 which extend substantially at right angles to the shield and toward the upright plane of the base-wall 19 and whichhave substantially upright edges 22 locatedof said base wall.

in the plane indicate laterally extending tongues at the bottom of the shield wall 20 which are adapted to .abut against the outer edges of. the upright strips 13 'of the window sash when the ventilator is in place.

23--23 indicate integral expanding spring tongues at the ends of the upright base wall 19, which are intended to form a yielding elastic filler block to engage wlthin the groove 15 and provide an anchor to hold the ventilator down 1n place on the window sill.

The laterally extending tongues 22, 22, by their engagement with the strips 13. at points spaced above the base of the ventilator, support it against turning movement inwardly on its base away from the window and in conjunction with the elastic tongues 23 act to securely lock the ventilator in position.

The ventilator is preferably made as above stated of thin sheet metal and the tongues 23, comprising as are resilient and thus are adapted to provide a spring'engagement with, the said In addition, as the metal of said tongues is comparatively thin, they may be distorted in one direction or the other so as to adjust them for proper engagement within grooves 15 of varying widths.

base of the ventilator.

The two sections 17 and 18 of the members of the shield are provided respectively at their top edges with telescoping beads l7 18 and at their bottom edges the one is formed with a straight edge 18 and the other with an upturned hooked flange 17 adapted to engage said straight edge.

In the use of the ventilator, it is brought to rest upon the window sill with the upright base 19 in engagement against the, shoulder 12 of the window sill 12. The two parts of the ventilator are then extended until the flanges 21-2l are brought into engagement with the side of the strips 13, 13 of the window frame 10. At the same time the elastic tongues 23 are brought into engagement with the inner faces of the strips 14 and the laterally extending tongues 22, 22 are brought against the inner faces of the strips 13, 13.

From an examination of Fig. 2 in which the ventilator is shown in the window it is manifest that the sash may be. brought down or raised to vary the window opening and that the said opening may be closed by bringing the bottom of the sash into engagement with the inclined wall 20 of the ventilator on a line near the top of the upright When the sash is brought into this position the window opening is entirely closed.

Apparently the ventilator may be adjusted within certain limits to windows of various'widths and may be quickly applied to a window or disengaged therefrom. Thus it is only necessary for the one-using the ventilator either in his office or in his home to have a few of the ventilators and instantly apply a ventilator to the particular window that is open. As the ventilator is so readily removable from the window sash, it in no way interferes with the proper cleaning. either of the glass of the window sash or of the window casing itself. The ventilator may be made of sheet metal which may be japanned or otherwise treated so as to produce a polished surface that may be easily cleaned, and as the ventilator has no pockets or other confined spaces for the accumulation of dirt. the advantage of its use from a sanitary point of view is apparent.

In order to permit the use of the ventilator with oldstyle windows which have no weights but are supported by pins or other devices when placed in an open position, my ventilator may be made as shown in Fig. 4. In this case the flanges 21 at the ends of the ventilator are provided at their upright edges with notched shoulders 22" which are adapted to be engaged with the sash in such manner as to support the sash when the same is lowered. These notches provide for the support of the sash at various elevations above the sill so as tovary the amount of the window opening.

I claim as my invention:

1. A ventilator having an upright base wall and a shield wall inclined upwardly and away from the plane of said base wall, the inclined shield wall having end flanges which extend toward the upright plane of said base wall, said ventilator being provided with elastic integral tongues forming substantially right angular extensions of said base wall which are located beyondv said end flanges and with other tongues extending substantially in the plane of said base wall and'being located above the level of said first named tongues.

2. A ventilator made in two parts, each. stamped from sheet metal and the two being plane of said base wall and being located,

above the level of the first named tongues.

3. A ventilator made in two parts, each stamped from sheet metal and the two be: ing constructed to telescope one upon the other so that the ventilator is adjustable-in length for windows of diiferent widths. said ventilator having an upright base wall and a shield wall inclined upwardly and away from the plane of said base wall, the inclined shield wall having end flanges which extend toward the upright planeof said base wall with their forward edges in which are formed stop shoulders substantiallv in "the same upright plane, the upright'base wall being provided at its ends beyond said flanges with integral extensions bent. to form elastic tongues extending substantially at right angles to said base wall and said flanges being provided with integral extensions cut to form other tongues located substantially in the upright plane of said base wall and above the level of said first named tongues.

In-testimony, that I claim the foregoing:

as my invention I afiix my signature in the presence of twowitnesses, this 24th day of November A. D. 1914..
